Filed: 1974-06-28
Abstract: 1427659 Exhaust driven turbochargers for IC engines MOTOREN-UND TURBINEN-UNION FRIEDRICHSHAFEN GmbH 28 June 1974 [2 July 1973] 28847/74 Heading F1G The invention relates to an exhaust driven turbocharger for an I.C. engine which comprises a control unit for adjusting the angular setting of the turbine inlet guide blades, the compressor inlet guide vanes, or the compressor outlet diffuser guide vanes, the control unit comprising a control slide and a hydraulic servo piston, and being disposed within the turbocharger casing between the turbine and the compressor. The turbocharger shown comprises a compressor impeller 13 and a turbine rotor 12 mounted on a common shaft 14 supported in a stator casing 11. A series of adjustably mounted inlet guide blades 16 are disposed adjacent the inlet of the turbine rotor, being rotatable by means of levers 27 which are connected to a common angularly movable ring 28. The control unit 21 is disposed within the stator casing and comprises a transverse bore in which a control sleeve 22 is slidably mounted; the control sleeve is acted on at its left-hand end Fig. 2 by pressure of air taken from the compressor outlet through line 23 and at its right-hand end by a spring 24. A pair of servopistons 25, 26 is disposed within the control sleeve to define fluid chambers 36, 37 therewith. A lever 29 integral with the ring 28 is disposed between the two servo-pistons being connected therewith by links 31, 32. In the event of a rise in compressor discharge pressure the control sleeve 22 moves to the right against action of spring 24 whereupon fluid under pressure in line 35 passes to chamber 36 causing piston 26 to move to the right whereby the lever 29 and so the ring 28 are caused to rotate so varying the angular setting of the turbine inlet guide blades 16; the chamber 37 is simultaneously connected to exhaust pressure in passage 38. The fluid under pressure in line 35 is lubricating oil supplied to the bearings. The parts in the control sleeve 22 are formed with an overlap 39 to prevent movement of the blades in response to fluctuations of discharge pressure.

Title: Printing presses
IPC: B65H9/00
Filed: 1971-06-21
Abstract: 1349167 Feeding and delivering sheets ING C OLIVETTI & C SpA 21 June 1971 [22 June 1970] 29025/71 Heading B8R A rotary printing press has a constant speed impression cylinder 7, means for transporting sheets to be printed, across a setting table 3, means for setting the moving sheets on the table 3 in lateral and longitudinal register with said impression cylinder and a transfer member, e.g. a suction cylinder 6, for transferring the sheets to the impression cylinder 7, the longitudinal registering means being carried by the transfer member which is driven at periodically variable speeds. A sheet may be separated from a pile 10 by suction heads 11 and fed via rollers 12, 13 and belts 16 to movable side registering plates (30), Fig. 1 (not shown), 31 and into contact with retractable front stops 49a, on the rotating suction cylinder 6, the peripheral speed of which, at this point, is slightly less than the linear speed of the sheet which is accelerated on the belts. As the cylinder 6 continues to rotate past the longitudinal registering position shown in Fig. 2, a rotary valve (43), Fig. 5 (not shown), connects suction pipes 36 fixed in cylinder 6 to a vacuum source, thus clamping the sheet in registered position, the cylinder then accelerating to the peripheral speed of the impression cylinder 7 whose grippers 96 grip the sheet released by the suction pipes and blown from the cylinder 6 by air jets issuing from apertures (102). A gripper chain 99 delivers the printed sheet to a stack P. As the cylinder approaches the longitudinal registering position cam operated sensing levers 66, normally held in a retracted position in the cylinder, are released so that unless a sheet is in a correct position underneath the cylinder for longitudinal registering, the levers 66 will be free to extend outside the surface of the cylinder 6, as shown in Fig. 6, this movement causing an associated lever 87 to pivot causing a roller 90 to actuate a microswitch 91 which cuts off suction to the pipes 36, the faulty sheet thus travelling past the retracted front stops 49a to a shoot 25 via rollers 26, 27.

Abstract: 249,201. Dixon, H. Dec. 17, 1924. Cameras with connected action between shutter and changing mechanism. -In a roll-film camera having an exposure indicator moved to one position on operating the shutter and back to another position on operating the film winding-mechanism, a pneumatic actuator mounted in the camera body and operated by the film mechanism is connected by a flexible air conduit to a pneumaticallyactuated element on the shutter casing, which upon actuating the film mechanism, restores the indicator from the position into which it was moved on actuating the shutter for an exposure. The indicator is carried on a spring-controlled pivoted lever 11, Fig. 3, and is set by a one-way trip arm 14 on the shutter lever 8 on actuating the lever 10 for an exposure. The indicator lever 11 is held in set position by a resilient detent 20, Fig. 6, which is associated with and released bv the pneumatically-actuated element 5. This element comprises an air chamber with a flexible diaphragm 15 and connected by a flexible tube 19, Fig. 9, to a pneumatic actuator 4, operated by the film winding-shaft 30. This mechanism is mounted on a single plate 24 within a recess in the camera body 3. The film winding barrel 25 has an inverted cup 26, Fig. 11, and a spiral cam 27 locked to the shaft 30 by a detent engaging a groove 29, so as to permit withdrawal of the shaft from the spool 31. The barrel 25 and cap 26 are also slotted to admit the end of a resilient lever 33. This lever is depressed by the cam on turning the film winding-handle, and finally springs back and compresses the diaphragm 32, Fig. 13, of the actuator element 4,thereby forcing air through the channels 36, 37, tube 40 and flexible tube 19, and effecting the release of the indicator. The diaphragm 32 is held against the lever 33 by an internal spring 41. The parts of the actuator 4 are assembled on the plate 24 by a single screw 44. The capacity of the air chamber 6 is larger than that of the chamber on the shutter, and the swivel connection 45 is so mounted as to provide a vent in the air train so as to ensure proper working and a resumption cf normal pressure when the parts are idle.

Anon. ; 46, Quai de Boulogne, Boulogne-sur- Seine, France.) Nov. 1, 1932, No. 30749. Convention date, June 17. [Class 40 (iv).] A non-contact making relay is used as a line relay common to a number of subscribers' lines. As shown, the relay comprises a thermionic valve normally biassed so that the anode current is insufficient to operate relay L. The cut-off relay CO when de-energized connects one side of the line to ground and the other side to the junction of a pair of resistances R1, R2 connected across the grid circuit in parallel with similar resistances of other lines and in series with a negative biassing battery. When one or more lines are looped as the result of calls, the variation of bias permits L to operate. The resistances are such that line leakage does not provide bias such as would enable the valve to pass current sufficient to hold L. Slow-torelease relay H, energized by L, operates M, S, which respectively complete a loop testing circuit over T and a driving circuit for magnet FM of the finder. When the line is found, T operates and connects its left hand winding to the c wire to energize CO, double connections being prevented since two T relays cannot remain operated in parallel. H is made slow releasing since M connects battery over T to the junction of resistances R1, R2 to increase the bias and therefore release relay L.
